' This invention relates to marking inachines and more particularly tomarking machinesdesigned to print a row of characters and arranged sothat the markers may be rapidly interchanged between printing operk 4 YI head and the setting mecl1anism;'and

ations; V x

The use of marking machines is common factories for manufacturing bootsand shoes and in many other places for imprinting a row of charactersupon a plurality of and when a marking machine is employed for such apurpose it is essential, for satisfactory use of the machine, that theoperator shall'b'e able quickly and accurately to interchange themarkers" upon the marking head without danger o't'soiling the handsor,in case the printing characters are heated, of burning the fingers. Anobject of the presentinvention is to provide a marking machine having animproved mechanism for setting the printing elements which will bearranged so that the operator may make the desired changes rapidly andaccurately without encountering any of the difiiculties above mentioned.I

With this object in View, a feature of the invention relates to a novelsetting device which may be brought into engagement with any one of aplural ity of adjustable markers. As illustrated, the markers are disksand displaceable retaining latches are provided for each of the disksand the setting device is so interconnected with the retaining latchesthat a ltlliCllflVlllCl] has been displaced to release one of the disksacts as a stop tor the setting mechanism to indicate to the operatorthat the setting device 1s in co-operative relation with the particulardisk which has been released The illustratedsetting device is mountedfor movement withln. the hubs of the various disks and is providedwithta v rod mounted for movement outside thedisks in a path whichintersects any latchwhich has been displaced.

These and other features of the invention as'point ed out in theappendedelaimswill be best understood from a consideration of thefollowing specification taken in connection with the accompanyingdrawings in which a v Figl'l is a side elevation of the machine\vith'part s broken away; Y

the driving pulley The connection between comprises a latch 38 pivotedupon the marking head in printing position;

- Fig. '3 'is'a f'ont elevation of'the machine with parts broken away;

Fig. 5 is a vertical section through the .marking head and the settingdevice.

The frame 10 0f the machinecomprises end nembers 12' and 14; between]which" power shaft 16 and a crank shaft 18 aresup ported. Power maybesupplied to the inachine in any desired manner but as hereinillustrated it will be used to r'otatea belt pulley 20 flooselymounted'upon the shaft '16 and adapted to be clutchedtosaid shaft by afriction disk 22. A pinion 2&(Fig. 3) upon the power shaft 16 mesheswith a gear 26 on' 'th'e' crank shaft- 18 and supplies power to rotatethe latter whe'n the clutch is closed.

It'is desired that the clutch shall be so arranged that the crank shaft18 will make one or more complete revolutions and then stop,

and to thisend a cam 30 is mounted upon the crank shaft 18 which actsagainst av lever 32 pivotally mounted'upon a transverse rod 33 andhe'ldagainst the camby aspring 35 to move a bifurcated lever 34:al'so'mounted on saidrod and at the desired time, pull the clutch disk22 out of engagement with 20 against a tension spring 3 6 1nounted uponthe power shaft 16.

the levers 32 and 34 is not a' fixed connection however, and it lever32"andresili'ently held against a stop screw 40 by a spring ll. Thislatch 38 engages the notch of a" horizontal rod 42 pivotally connectedat one en'd to the bifurcated lever 34: and at, the other end to atreadl e rod 44:.

This places the mechanism in such condition that an'upward niovementofthe trea dle rod lt under the control of the operative releases thehorizontal rod 42 and allows the spring 36 t'o throw the clutcliintooperative engagemerit with the driv in'g pulley '20; thereby supplyingpower to the crank shaft 18 and eiiecti'ng rotation of the latterlAssoon as the treadle rod 44 is released the operator the will a'gainslip intdposition for engagement-with the notch" in the horizontal rod42 so that the cam 30, aeting throughthe lever 32and'the now connectedlev'er 34, will Fig. 2 is a fragmentary view showing the become effectiveto throw out the clutch at the completion of a full revolution of thecrank shaft 18.

The marking head is supported in a hanger 50 which is pivotally mountedupon the outer end of parallel links 52 and 54; which are pivoted withinthe frame of the machine, so that the hanger 50 is maintained insubstantially vertical position as it is moved up and down to bring theprinting characters into and out of engagement with the work. The link541 is extended to the rear, as shown in Fig. 1, where it; is connectedby means of a link 56 with a crank 58 on the crank shaft 18.

The marking head comprises adjustable markers for printing characters,which will be described more in detail and ink is supplied to saidmarkers bynieans of an inking device comprising a rotatable cylinder 60mounted upon the frame of the machine and adapted to be kept coated withink from a reservoir 62 placed over the rear upper quadrant of thesupply cylinder 60 in a position where it may conveniently be filled asdesired and, by virtue of a scraper plate ca adjustable by means of ascrew 66, may be caused to supply a film of marking material to therotatable cylinder 60. To transfer the ink from this cylinder to themarkers a transferring roll is carried upon the outer end of an arm 7 2pivoted at its upper end in the frame of the machine and actuated bymeans of a link 7 1 which is connected to an extension 76 upon the upperparallel link 52 so that it is brought into position to wipe across themarkers as the marking head moves into inoperative position and to wipeacross the supply cylinder 60 as the marking head moves into printingposition, as'shown in Fig. 2. It will be noted that the transferringroll is carried upon a pivoted extension 7 8 ofthe arm 7 2 which isspring pressed upwardly by a spring 80 to hold it resiliently inengagement with either the markers or the'supply roll as thetransferring roll 70 is caused to wipe across first one and then theother.

It is frequently desired to use a machine of this type for marking astack of similar pieces of work, as indicated in Figs. 2 and a, and tofacilitate the use of the machine for such an operation a work table 82is provided having a post 8 1 slidably mounted in a suitable bearing 86formed at the outer end of a bracket 88 on the frame of the machine.Interposed between this bearing and the work table is a spring 90 thetension of which may be adjusted by means of a screw 92 and the range ofmovement of the table with respect to the bearing sleeve is limited bythe engagement of a stopscrew 9 1 in the sleeve with a slot 96 in thepost'8 1. A.

holding latch 98 is then provided which has a locking cam positioned forengagement with the side of the post 84 to hold it in adjusted positionwhen said latch 98 is pressed downwardly and to release the table forupward movement under the tension of the spring 90 when the latch 98 ismoved to upward position. Mechanism is then provided for automaticallycontrolling the latch 98 so that the table is released for automaticpositioning by means of the combined action of the marking head on thestack of'work and the tension of the spring 90 with the result that thepressure of the marking head upon the work is kept uniform regardless ofthe number of pieces of work underneath the marking head. This allowsthe operator to hold the work in the manner indicated in Fig. 2 and toallow one piece after another to drop into position forengagement by themarking head without fear of producing an excessive pressure of themarking head when stack of pieces has accumulated. The au tomaticmechanism controlling the latch 98 includes a rod 100 pivotally mountedat 102 upon an extension 101'- of the parallel link 51 and slidablyengaged at 106 with the outer end of the controlling latch 98. A head108 is provided upon the rod 100 to lift the latch to release the post8% of the table when the rod 100 has moved to upward positionaccompanying a downward movement of the marking head. When the markinghead has moved to inoperative position, however, the rod 100 is moved tothe position indicated in Fig. 1 and thereby tensions a spring 110surrounding said rod and interposed between the controlling latch 98 anda stop 112 on the rod. This causes the controlling latch 98 to biteagainst the post 84 of the table and hold it againstvthe tension of thespring 90.

The arrangement of the marking head is best shown in Figs. 3, 1 and 5from which it will be seen that the lower 'end of the hanger 50 isbifurcated to provide vertical arms 11 1 and 116 and a hollow supportingmember 118 is mounted upon the arm 116' by screws entering a flange 120in said hollow support. Surrounding this hollow support and rotatablewith respect to it is a slotted sleeve 122 having oppositely positionedslots of which parts are filled by the rods 124: and 126 of the settingdevice. A plurality of adjustable markers are provided in the form ofdisks 130 rotatably mounted upon the slotted sleeve 122 and in theillustrated embodiment these disks are provided with teeth upon theirexternal peripheries carrying printing type-faces. It should be notedthat the setting device to be described is not limited in use to anarrangement in which the type-faces areplaced directly upon the diskswith which the setting device is associated but may also be used with anarrangement (not shown) having a plurality of series of disks interisdesiredto-change the position.

engagedwith one another so that the. typetaces are carried upon one ofthe ser es which is remote from the particular series adjusted by thesetting device. These disks 130 are notched upon their inner peripheriesas indicated in Fig. 5 so that there is a. notch corresponding to each,of the teeth upon the outer periphery. Vi hen in printing position (bywhich is meant-an alined position ready to print) the notches or thevarious disks will be alined to form the grooves which appear in Fig. 5.This arrangement enables the rod 126 of theset ting device to beprovided with a tooth 132 ging the notches upon the inner peripheri s ofthe disks and is slidable transversely of said disks to-bring' it into,co-operat-ive relation with any particular disk of which it Preferably,the positionot the various disks upon the support is determined by meansof displaceable pivoted retaitning latches' 134 which maybe of anyconvenient construction and preferably are arranged substantially asshown in U. S. Letters Patent No. 984,588, granted February 21, 1911 onthe application of F. V. Merrick. It desired for the particular use towhich the. machine put, a size lever 136 (Fig. 3) may be providcd whichis arranged according to the principle described in said patent so thatits operation causes the size wheels to be changed step by step toindicate a series of sizes and half sizes. The rods 124 and 126 aremounted upon a head 140 (Fig. 5) to which thereis connected a settingwheel 142 and bracket 144 is pivotally mountedupon this head and heldrigidly against movement along the axis of the disks. This bracket 144carries a rod 146 passing through a bearing 148 (Fig. 4) in the arm 114and moving in a path intersecting the position of the retaining latches,134 when any one of them has been displaced to release the correspondingdisk' It should be noted from F 5 that the length of: the rod 146 issuch that itwill engage the side of the retaming latch corresponding tothe particular disk-with which the tooth 132 of the setting rod 126 ispositioned in engagement.

"When the operator desires to adjust the markers upon the marking head,he will depress'a particular latch 134 corresponding to the disk whoseposition it is desired to change. The setting device may then be inovedlaterally until the rod 146 contacts with the particular latch which hasbeendisplaced. This positioning movement of the setting device willbringthe tooth l32 upon the rod126 in engage nentwiththe notch on the. inner.periphery of the particular disk which has been released by thedisplacement then be rotated by' turning the wheel 142 after which theoperator will allow-the latch the disks are held 'tained in position bymeans of a members ity is particular markerv with which. the displace--ablememberisassociated.

If it is desired to heatthedisks of the marking head an electric cartridge unit 150 may beinserted within the hollow support 118 thereby tosupply heat to saiddisks. The arrangement illustrated includes a type carrying plate 152 1)carried in aline- I mentwith that row of printing type-races which is inset position and'this plate is relatch 15.4.
